' 'l'a if nil/om it run); woncmm lte it known that I, \Vitnr/m A. Sominunor, a eitize'noF-the t'nited States. residing at llrie, in the eounty oi llt'le and State'ol' Pennsylvania. have invented new and u selul improvements in l'ipetlrgan Aetions, of

whieh the following, is a. speeitieation. This invention relates topipeorgan aetions oi the type embodyinga series of individual eompressed air che ts or bores t'rom whieh ttn-air is admitted t and I for so'linding'the several pipes or reed arranged respee- 'tiely above so i ehests, together with a main key ,eontrollm-l air bok or ehest from whieh the air is admitted' to and t'or eontrolling o 'reration oi eontroller valves arranged in the individual rites-ts. I ''lheinvention has for its objeets to provide a simple and "etlieient means for elosing the individual ehests whereby ready augeess may be had to the interiors there- "oi in the operation of eleanivn, or repairing the organ and onewherein the individual controller valves are attz'li'ed to and for removal with.the groove boards through the medium oi which the ehestsare elosed, in

eorda'm-e with the invention. -With these and other objects in view, the invention oomprises the novel features of eonstruetion and eomliinatiou of parts morelully hereinafter deseribed.

in the aeeompanying drawing, there is shown a rt-ieal stadioual view taken from front to rear through portion of an organ-=u-tion,'in which the invention is embodied. i

"Referring to the drawing. it will be seen that the organ ei'nbodies a plurality oi individual ehests or boxes whieh ar normally tilled with air under pressure supplied from. a suitablesouree above whieli are sustained pipesor reeds 2 and having eonununieation at: their l l ower ends with the respeetive ehests through the medium of openings or ports 3 normally elosed by valves 4, the v'ertieal movable stems 5 oi whieh are ida'bly' arranged in bearings i and rest'at their lower endssm bellows 7 whit-h are normally expanded for 'maintaining the valves seeure'ly seated to elose the ports,the valves being further aeted upon for this piniose tln'oughthe medium of springs 8 eoiled upon the -tents"'rtoaet lnitween the bearings ti and v'alves. The "tionalso ineludes amain valve ehamher ft eontainiug nompressed air and huvinghv ke y-eontiolled inlet port (Heading from the main inner box or ehest not shown, "n d admitting air to and for expamliug a normally eollapsed bellows ll en whieh rests the lower end o'l' 'ei'od JIZearryinga pairot' vertieallyspar-ed valves tnd 'l'l disposed to net oppositely l'or elosing u."

ln aeeordanee with the invention, the bottoms of the individual eompartments l are elosed by m ans of a plurality oi groove boards l8, one for eaeh eompartment, and detaehably seemed in pluee by fastening members oi serews l9. whereby the 'boards may be individually removed, it being noted at. this point that. the p; "ige H5 is formed in part through the boards IS, and t'urtlu-rmore that the valve t3 normally stands in open position toadmit air from the eonmartnn-nt 9 through the pa sage to and portl7't'or maintaining, the bellows expanded while the lve M a the same time stands in elosed position for eutting otf eolnmuuieation between the passage ltiand external atmosphere.
